        <title>CSS Test: Absolutely positioned inline replaced element with 'direction' as left-to-right, 'auto' specified for 'margin-left', 'margin-right', 'right' and intrinsic width</title>

        <meta name="assert" content="The intrinsic width is used if 'height' and 'width' are 'auto'. Computed value of 'auto' for 'margin-left' or margin-right' on absolutely positioned inline replaced element becomes a used value of '0'. If at this point there is an 'auto' left (like right as in this test), solve the equation for that value." />

			1in			: left
			0px (set)	: margin-left
			1in			: width (intrinsic width)
			0px (set)	: margin-right
			(solve)		: right
		=========================
		    2in			: width of containing block (2in)

		    Therefore , the used right offset must be 0px
		    so that the contraining equation gets balanced.
